Lightning talks

We're looking for good short/lightning talks.

A lightning talk is a very short, more or less impromptu talk on
any subject relevant to the conference. It can be on anything bearing
on Lisp, Scheme, or related languages. It need not be on a profound
topic or a research project. It can be as simple as:

Here's a good application that we wrote in Lisp.

Here's a useful Lisp library that you might want to know about.

Here are some interesting things about my Lisp development tool.

I have this provocative/outrageous opinion.

Please give me feedback about this idea.

Alice and I will debate the following point.

The format is five minutes of talk (this limit will be
strictly enforced---speakers will be cut off in
mid-sentence if necessary) followed by two minutes of
question-and-answer. Speakers may project images from a laptop;
laptops should be connected and disconnected quickly during the
two-minute question-and-answer intervals. Three lightning talks were
accepted by the program committee and written summaries will appear in
the printed proceedings; other lightning talk slots will be allocated
at the conference registration table on a first-come, first-served
basis.

There's a nice web page here
about short/lightning talks and a and a longer one with advice here.
